Abstract
Methods and systems for recovering sulfur dioxide from a Claus unit process emissions stream are provided. The method comprises the steps of generating a process emissions stream from a thermal oxidizer or other combustion device, introducing the emissions stream to an SOremoval system, introducing the SOrich stream from the SOremoval system to a COremoval system, and introducing an enriched SOstream back to the Claus unit. The SOremoval system can include one or more SOselective membranes. The COremoval system can include one or more COselective membranes.
